SA driver on phone when motorcyclist hit

A driver who was in the middle of a birthday phone call when she hit a motorcyclist, whose leg had to be amputated, has avoided a jail term.

"Holding a phone to your ear while driving, and in particular when turning your vehicle, is a highly reckless and dangerous act," Judge Paul Rice told Frances Jacobson in the South Australian District Court.

In his sentencing remarks published on Monday, the judge said the victim had outlined how his life had been destroyed by having to have his leg amputated above the knee.

"I suggest that you should keep a copy of his victim impact statement near to you and read it from time to time to remind yourself of the consequences of your actions."

Jacobson, 52, pleaded guilty to causing serious harm by dangerous driving in March 2012 in Adelaide.

She was given a two-year jail term, which was suspended upon her entering a two-year good behaviour bond, and disqualified from driving for 10 years.

The judge said Jacobson was in the middle of a phone call to a friend, who was having a difficult time on his birthday and was concerned no one would call him.
